To all whmn it may concern:

Be it known that I, CHARLES A. KING, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented a new and useful Breech-Loading Gun, of which the following is a specification.

This invention relates to the construction and application of the hardened bolt-plate of a breech-loading gun.

The object of the invention is to provide a bolt-plate which can be conveniently applied so that it will fit very tightly, which may be easily removed when desired, and which is cheap to manufacture, whereby a gun may always be provided with a bolt-plate which is not liable to break and which insures a close locking of the parts.

The invention resides in a T-shaped boltplate which is arranged to be fastened to the lug of a breech-loading gun in such manner that it will be held tightly in place and yet can be conveniently removed without requiring the holding parts to withstand any par ti'cular pressure or strain.

This invention is applicable to both double and single guns, but is illustrated in connection with a double gun.

Figure 1 of the drawings shows a side elevation of a portion of a gun provided with this improvement. Fig. 2 shows a side view of the breech end of a pair of barrels provided with the improved bolt-plate. Fig. 3 shows an end View of these barrels and this bolt-plate. Fig. 4 shows an enlarged side view of the bolt-plate, and Fig. 5 shows an enlarged end View of the bolt-plate.

In the views, 1 indicates the barrels, which are hinged to the front end of the breechframe 2 by the pivot-pin 3 in the common way. Carried by the breech-frame is the upper surface for receiving the bolt and a fiat front surface which fits against the lug, and it has along the bottom a longitudinal fin 14, that is shaped to fit in the longitudinal s0cket 12 in the lug. A perforation is made transversely through this fin. The bolt-plate is placed upon the lug with the [in in the socket, and then a pin 15 is driven through the perforations in the lug and plate for holding the parts in position. It is preferred to drill the perforations in such way that the pin when driven in will cause the parts to draw tightly together. The bolt plate is made of hardened material, so as to resist wear; but the lug itself is made of softer material. This bolt-plate is simple to shape, and the seat for it at they end of the lug is cheap to form. This bolt-plate can be quickly placed in position'and fastened very tightly, and if it becomes worn or broken it is a simple matter to drive out the pin and substitute a new plate for that which is worn or broken.

' The plate which receives the wear is not weakened by the holding-pin, which is so driven as to insure a tight fitting of theparts. This invention not only simplifies the con struction of the gun, but also increases its life, for the reason that the gun need never be without a tight-fitting bolt-plate.

The invention claimed is r 1. In combination with a breech-loading gun, a locking-lug having a rearward extension, a bolt-plate on top of the rearward extension of the locking-lug, a fin projecting downwardly from the bolt-plate into a slot in the locking-lug, a pin extending through the lug and the fin and holding the bolt-plate in place, and a bolt adapted to project forwardly over the bolt-plate, substantially as specified.

2. In combination with a breech-loading gun, a lug having a rearward extension provided with a longitudinal socket, a bolt-plate having a pin adapted to fit the socket, and a pin extending through the rearward extension of the lug and the fin for holding the boltplate in position, substantially as specified.

3. In combination with a breech-loading gun, a lug with a rearwardly-extending projection, a T-shaped bolt-plate carried by the lug, and a pin for holding the bolt-plate in position, substantially as specified. a
